DETAILED DESCRIPTION OF THE DISCLOSURE

The specific implements of the present disclosure will be further described below in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to illustrate the technical solutions of the present disclosure more clearly and cannot be used to limit the protection scope of the present disclosure.

Referring to FIGS. 1-6 , the instant water heater includes a housing 1, a water inlet pipe 2021, a water outlet pipe 2022, a mounting member 5, and an electric controller 6.

The housing 1 has a heating container 2 inside. The heating container 2 includes a cap 202 and a water tank 201 detachably connected to the cap 201. As shown in FIG. 2 , the upper part of the water tank 201 is detachably connected to the cap 201. A heating pipe 3 is located within the water tank 201.

The water inlet pipe 2021 is in communication with a first side of the cap 202.

The water outlet pipe 2022 is in communication with a second side of the cap 202. The water inlet pipe 2021 and the water outlet pipe 2022 are connected to two sides of the housing 1, respectively.

The mounting member 5 is configured for securing the water tank 201 to the housing 1.

The electric controller 6 is configured for controlling work process of the heating pipe 3.

When in use, the electric controller 6 controls the on/off state of the heating pipe 3. External water (e.g., cold water or the like) comes from external and is introduced into the water inlet pipe 2021. The external water enters the heating container 2 through the water inlet pipe 2021. The water which entered the heating container 2 can be heated up by the heating pipe 3 and then output for use. In the present disclosure, the mounting member 5 secures the water tank 201 to the housing 1. The water inlet pipe 2021 and the water outlet pipe 2022 are connected to two sides of the housing 1. By this design, the water tank 201 and the cap 202 can be secured at three points, ensuring the assembly stability of the heating container 2 without using extra locking components. The instant water heater as provided, therefore, has more space for distribution and installation of other components including the SCR 10, the over-temperature protector 11, and the terminal blocks 12.

As shown in FIG. 2 , an outflow end the water inlet pipe 2021 extends into a middle part of the cap 202 and bends downward. A bend portion of the water inlet pipe 2021 is connected to a conduit 7 downwardly. A bottom of the conduit 7 is fitted into a secure seat 8. One end of the secure seat 8 distal from the conduit 7 is securely abutted against a tank bottom of the water tank 201. A water outflow port is provided on the secure seat 8 to communicate with the conduit 7. In this embodiment, the conduit 7 is coated with catalyst material layer 19 on the inner wall for preventing scaling.

The arrangement of the conduit 7 and the secure seat 8 allows the introduced water to be guided into the tank bottom of the water tank 201, so that the external water (e.g., cold water) can be fully heated up and then output. This also can further improve the assembly stability of the water tank 201 and the cap 202.

A water inflow end of the water inlet pipe 2021 is connected to a joint pipe 4. The housing 1 includes polygon connection holes 101 respectively located at positions corresponding to the joint pipe 4 and the water outlet pipe 2022. Polygon connection blocks 9 adapted for the polygon connection holes 101 are respectively arranged on the joint pipe 4 and the water outlet pipe 2022. The cooperation of the polygon connection hole 101 and the polygon connection blocks 9 allows the join pipe 4 and the water outlet pipe 2022 to be connected to the two sides of the housing 1.

The cooperation of the polygon connection hole 101 and the polygon connection blocks 9 allows the join pipe 4 and the water outlet pipe 2022 to be connected in a steady and anti-rotation state. This not only improves the assembly stability of the cap 202, but also prevents the influences caused by connections of external cold water pipeline or the hot water pipeline.

The heating pipe 3 is connected to the electric controller 6 via a SCR 10 (silicon controlled rectifier), and an over-temperature protector 11.

On basis of the water inlet pipe 2021 and the water outlet pipe 2022 connecting to the two sides of the housing 1, the over-temperature protector 11 of the present disclosure may also be secured to a side wall of the water tank 201. The SCR 10 and the terminal blocks 12 are arranged on a second side of the housing 1 opposite to a first side thereof which accommodates the heating container 2. As shown in FIG. 2 , the SCR 10 is located above the terminal blocks 12.

The join pipe may be made of metal material. An installation platform for heat dissipation is located on the join pipe 4 at a position corresponding to the SCR 10. The SCR 10 is secured on the installation platform.

Due to the improvement of the assembly layout of each component of the present disclosure, the SCR 10 is located on a lower side of the joint pipe 4. Therefore, the installation platform for heat dissipation can be arranged on the joint pipe 4, so as to create heat dissipation for the SCR 10. On the basis of being compact and reasonable, the practical effect of the present disclosure is further improved.

A secure bracket 102 is arranged on the housing 1 for supporting the water tank 201. An mounting groove 2011 is located on the water tank 201 at a position corresponding to the secure bracket 102, so that the cooperation of the secure bracket 102 and the mounting groove 2011 allows the water tank 201 to be connected to the secure bracket 102. The mounting member 5 is abutted around an external side of the mounting groove 2011 on the water tank 201, and both ends of the mounting member 5 are secured to the secure bracket 102 via locking screws 13. The mounting member 5 is arc-shaped. The water outlet pipe 2022 extends to outside of the housing 1 and is attached to a joint 14.

The mounting groove 2011 and the secure bracket 102 cooperates to assemble the water tank 201 to the secure bracket 102, then the arc-shaped mounting member 5 clamps the external side of the mounting groove 2011 of the water tank 201 to form a steady fixation for the water tank 201 of the present disclosure.

The water tank 201 is made of metal material. The cap 202, the water inlet pipe 2021, and the water outlet pipe 2022 are made of plastic material by integral molding, respectively. The water tank 201 and the cap 202 are connected by flange connection. A sealing ring 15 may be located and squeezed between the water tank 201 and the cap 202. This arrangement allows the assembly sealing between the water tank 201 and the cap 202, and also effectively reduces the manufacture cost. Moreover, this arrangement further optimizes the assembly convenience of the water tank 201 and the cap 202.

A water inlet temperature sensor 16 and a water outlet temperature sensor 17 are arranged within the water inlet pipe 2021 and the water outlet pipe 2022, respectively.
